IMPROVEMENT IN FLUTING-MACHINES.

Specification forming part of Letters Patent No. 220,586, dated October14, 1879; application filed March 4, 1879.

To all whom it may concern:

Be it known that I, JOHN E. DONOVAN, of Cincinnati, in the county ofHamilton, and in the State of Ohio, have invented certain new andusefulImprm ements in Fluting-Machines and do hereby declare that thefollowing is a full, clear, and exact descriptionthereof, referencebeing had to the accompanying drawings, making a part of thisspecification, in which- Figure 1 is a perspective view of my improveddevice as arranged for use. Fig. 2 is a side elevation of the same, onesection of the frame being removed to show the interior construction ofparts. Fig. 3 is a cross-section upon line m w of Fig. 2, and Fig. 4 isa plan view of the lower side of said device.

Letters of like name and kind refer to like parts in each of thefigures.

The design of my invention is to simplify the construction and toincrease the efficiency and ease of operation of mechanism employed forfluting fabrics, to which end it consists, principally, in the meansemployed for moving the adjustable roller toward or from the fixedroller, and for securing the same in position, substantially as and forthe purpose hereinafter set forth.

It consists, further, in the machine as a whole, its several parts beingconstructed and combined to operate in the manner and for the purposesubstantially as is hereinafter specified.

In the annexed drawings, A represents the frame of my machine, whichconsists of a base having sufficient horizontal dimensions to furnish afirm bearing, and a standard that extends in a curve rearward andupward, as shown in Fig. 1. From the upper end of the standard of myframe A an arm, A, extends horizontally forward to or slightly beyondthe front end of the base, and at its end extends downward a shortdistance, and at the inner side of such portion is provided with a roundbearing-pin, a, that extends horizontally rearward about one-fourth ofan inch.

The frame Ais cast hollow, and is constructed in two sections, whichunite upon a central longitudinal line, and are secured together bymeans of a screw, B, that passes through two cars, a, which are providednear the lower end of the standard, and a strap, G, that extendstransversely across and is secured to the lower side of each section, asshown in Fig.4. Within the upper end of the standard of the frame A, ina line with the bearing-pin a, is provided an opening, a whichcorresponds to and receives the journal d of a fluted roller, D, ofusual construction, which roller has an axial opening, 01, thatcorresponds in diameter to the diameter of said bearing-pin, and, at theouter end of said roller, receives the same, the arrangement bein g suchas to enable said roller to rotate freely within said opening and uponsaid bearing-pin. Below the opening or bearing a is provided a secondlarger opening, a which passes through the standard, and permits of thepassage of the journal at of a second fluted roller, D, which rollerrests within and is supported by a frame, E, (shown in Fig. 2,) that hassubstantially the shape, in reverse, of the arm A and is provided with abearing-pin, c, for the outer end of said roller, and for the inner endor journal at has a half-box, within which said journal rests. TheframeE is supported upon arod, F, which atits upper end is secured tothe same, and from thence passes downward through the horizontal centerof the base of the frame A and through the strap 0, the constructionbeing such as to permit said frame E, with its roller, to be movedvertically toward or from the upper roller.

In order that the lower roller, D, may be ad j usted to and secured invertical position, the tbllowing-described mechanism is employed: Fittedloosely upon the rod F is a collar, G, which is provided at its upperend with a radial flange, g, as seen in Fig. 2, and is capable of movingvertically over said rod. Upon the upper end of the collar G is placed avolute spring, H, which encircles the rod F, and at its upper end bearsagainst a pin, f, that passes radially through said rod. Passing throughan opening, a in the rear side of the base of the frame A is a lever, I,which has the form shown in Fig. 1, is pivoted upon the screw B, and atits inner end is forked, and its prongs t caused to loosely embrace thebody of the collar G below the flange g, the arrangement being such asto enable said collar, and with it the rod F, frame E, and roller D, tobe moved upward or permitted to drop downward by depressing or raisingthe outer end of said lever.

In order that the roller I) maybe locked in position when adjustedthereto, a pawl, K, is pivoted within the lever I, just outside of itspivotal bearing B, the outer end of said pawl being extended beneathsaid lever to or near the end of the same, while the inner end of saidpawl projects upward and inward in a curve, and is provided upon itsupper side with a Series of teeth, k, that have an inward and up wardinclination, and by the weight of the said outer end are caused toengage with the upper edge of the opening a, so as to lock said lever inplace and prevent the lower roller, D, from dropping downward.

To raise the lower roller, D, it is only necessary that the outer end ofthe lever 1 should be pressed dbwnward, the pawl K being automaticallytripped and caused to reen gage with its stop; but when it is desired todrop said roller it is necessary that said lever should be grasped bythe hand and the outer end of said pawl raised by the fingers of theoperator until its inner end is released from engagement, after whichsaid roller is free to be moved to position.

A crank, L, being placed upon the projecting journal of one of therollers-preferably the lower roller--the machine is ready for use, inthe ordinary manner, said rollers being heated by hot metal blocksplaced within the interior of each, and the goods to be operated uponpassed between their tluted peripheries.

Any desired degree of pressure of the rollers upon the fabric may beproduced by the adjustment of the lever I, and said rollers may bereadily separated for the purpose of inserting or removing articles bythe same means.

The rollers D and I) are held together with ayieldin g pressure, whichenables goods of varying thickness to pass through, and in consequenceof the form of the spring ll, greater strength, durability,andelasticityare secured than would be practicable within the limited spaceby use of any other form of spring.

To facilitate the removal or replacement of the fluting-rollers aportion, A of the standard of the frame A, directly over the journals ofsaid rollers, is separated from said standard and may be removed whendesired. A screw, M, passing through the upper end of said part or capA, with its threaded end contained within a correspondingly-threadedopening in the opposite section of the frame, secures said cap in place.By withdrawing said screw and removing said cap said rollers can beeasily and quickly taken out or replaced.

A clamp, N, swiveled to or upon one side of the base of the frame, andprovided with a binding screw, n, enables the machine to be fastened toor upon the edge of a table or other like support, so as to be moreeasily operated.

If desired, the standard may be cast separate from the base and boltedthereto at its lower end, as shown by dotted lines of Fig. 2, in whichevent said standard would be cast in one piece, and access to itsinterior had through the cap A Having thus fully set forth the natureand merits of my invention, what I claim as new 18-- 1. In aflitting-machine, in combination with the vertically-adjustable frame E,the rod F, collar G 9, spring 11, forked lever I, and pawl K,substantially as and for the purpose specified.

2. The hereinbefore described fluting machine, consisting of thesectional base A, provided with the arms A cap A, the strap (J, and thescrews B and M, the rollers D and D, the adjustable frame E, thesupporting-rod F, the collar G g, the volute spring H, the forked leverI i, the pawl K k, and the crank L, said parts being constructed andcombined to opcrate in the manner and for the purpose substantially asspecified.

In testimony that I claim the foregoing I have hereunto set my hand this21st day of February, 1879.

JOHN E. DONOVAN.
